To aZZ whom 2'25 may concern.

Be it known that I, EDWARD J. Von Pam, a citizen of the United States,residing at Dayton, in the county of, Montgomery and 1 State of Ohio,have invented certain new and useful Improvements in Oash-Regis ters, ofwhich I declare the following to beber 15, 1913 and a reference may behad to,

said application for a specific embodiment of this invention.

In previous constructions the perforator is usually carried by arotatable element having an invariable movement and the perforator teethare so arranged that all are brought into play at the same instant. Thiscauses the machine to run hard at that particular point of theoperation. .One object of the present invention is to provide a perforator so arranged that the teeth, while they are carried by aninvariably moved rotatable element and perforate in a straight line atright angles to tl e length of the strip of material, are not broughtinto play simultaneously, but one after the other, thereby distributingthe perforating operation over a greater part of theoperation of themachine and making the machine run more easily.

Another object of the invention is to pro vide improved means forholding the paper against or opposing it to the teeth of the perforator.V

In previous constructions a roller of rubber or similar yieldingmaterial was used, into which the teeth of the perforator sank afterthey passed through the paper. Such rollers are necessarily short livedand therefore unsatisfactory, a condition which the applicant remediesby using an improved roller made of steel or other durable material andarranged to accomplish the same result as the rubber roller.

With these and incidental objects in view, the invention consists ofcertain novel features of construction and combination of parts, theessential elements of which are set forth in appended claims, and apreferred form of embodiment of which is hereinafter described. I

l/Vith reference to the drawings which aocompany and form part of thespecificat1on: 4 I

roller 82, carrying the perforator blade 101' and a roller 31 composedof steel or similar material and having annular grooves 127,

Patented oet. as, 1917. I

Fig. 2 is a top view of the perforating de-' corresponding to the teethin the perforator.

The sh-aftBO, upon which the roller 81 is loosely mounted, has securedthereto a gear 79 and a disk 129. The gear 79 may be connected in anydesired way to a part of the machine of which the present invention ismade an element. Fastened to the roller 81 is a disk 133 and a gear1-31. In order to allow the roller 81 to move laterally on its shaft,the roller 81 is driven through studs 135, secured to the gear 131, andprojecting into holes in the disk 129'. The perfora'tor roll 82, looselymounted on the shaft '95, has rigidly secured to it the disk 13 1, andthe gear 132. The gear 131 meshes with the gear 132 and the disk 13?:extends into the recess between the disk 134: and the gear132,-so'th'a't any lateral movement of one roller will be imparted tothe other and the teeth of the perforator and the grooves of the roller81 will always be held in 'alinement. Both the roller 82 and the roller81 are set at air-angle to the length of'the strip of material 83 to beperforated, as shownjin Fig; '1, but parallel one to the other with thestrip 83 passing between them. The roller 82 is cut away, as shown inFig. 5-, and the is at right angles to the edges of the strip 83. Theline of'the teeth also conforms to the curvature of the r ll 82 and whenthe rollers are rotated, the teeth the end 138, are first brought intoengagement with the paper and the other teeth are carried insuccessively until the ones at the end 139 have performed their work. Bythis arrangement of the blade, the teeth are not carried into contactwith the strip simultaneously, but at the same time the line ofperforation is at right angles to the length of the strip. However,owing to the angular position in the printer of the perforator rollers,the path of rotation of the teeth is not parallel to the length of thestrip and the tendency would he, therefore, to pull the strip to oneside while the perforator teeth are in engagement with it To olfsetthis, there is cam into the slot of which there eX- tends anantifriction roller 14:2 carried by a bracket M3 secured to the frame ofthe device. At the instant that the teeth 138 of the perforator engagethe strip the point 14-1, Fig. at, of the cam slot strikes the roller1%2 and the rollers 81 and 82 through the connection established by thedislrl33 are both shifted laterally on their shafts until the point i lsof the cam slot passes the roller, at which time the last tooth at theend 139 of the perforator passes out of engagement with the strip. Thesurface 146 of the cam then shifts the rollers back to their normalposition, in which position they remain during the rest of the rotation.

The portion M l to 1&5 of the cam slot is so graduated that during thetime the teeth of the perforator are working their line of 1 travel isin a plane parallel to the edges of the strip instead of being as it isnormally at right angles to the inclined shaft 95. This overcomes thetendency to pull the strip to one side and causes it to movecontinuously in the direction of its length, even while the perforatorteeth are in engagement with it.

The actuation of the rollers may be intermittent or constant as desiredand the strip of material may be moved any desired distance betweenperforating operations without departing from the present invention.

While the form of mechanism herein shown and described is admirablyadapted to fulfil the objects primarily stated, it is to be understoodthat it is not intended to confine the invention to the one form ofembodiment herein shown and described, as it is susceptible ofembodiment in various forms, all coming within the scope of the claimswhich follow.
